Abstract: To the question of measuring the moving object pose, a high speed spatial pose measurement system based on binocular vision photography was designed. The system can record the course with high precision synchronization. Geometry constraint relation of the special markets and optimization algorithm based on coordinates of multi-points were used in the pose algorithm of the moving object. Experimental results and theoretical analysis prove that the pose measurement method is correct and reliable. The frequency of the pose measurement system is 100 frames per second. The measurment error of the pose angle is less than 0.04°.
